Etymology is interesting and useful, but it does not always explain the current definition of a word. Although the source of complicit is silent about the nature of the complicity, our present definition requires complicity to be toward nefarious acts. If one is peripherally involved in the commission of a good deed, he/she is not complicit to the action. It is not ours to reason why, it is but ours to accept what the dictionaries say. Well, not always. We can march to the beat of a different drummer, but we risk being out of step with the total system. If your drummer tells you that complicity can be applied to good actions, by all means try using it that way. Don’t be surprised, though, when the world does not understand you.
